Reasons and Solutions

1.Do not edging the laminated glass until the laminated glasses have
been cooled for 24 hours after pulled out from the EVA GLASS

2.When edging, SOME heat will be created in the edges, which will do
harm to the EVA FILM adhesion, so please use more water to cool the
heat when edging the laminated glass.

3.Please edging slowly and tenderly.

4.If the EVA FILM interlayer you use is not good quality, then the
adhesive between the EVA Film and glass surface may be weak, then it’s
easy to delaminate when edging.
